Add animation effect to fonts glyph. Can scroll/rotate glyphs, left, right(x), up and down(y) within fonts viewable area(fonts acsent to descent height and its delta width)
Added a gap option, zero means no gap, so scroll looks like glyph is rotating or sliding. Gap value greater than fonts viewable area makes glyph scroll out it or back in.
void setFontScroll(int8_t x, int8_t y, uint8_t gap=0)
I used this to make a 'V' into an animated chevron >> status icon. This feature scrolls relative to glyph, so changes with rotate direction
